After comparison, it was found that with the increase of the initial concentration of MO solution, the HNTs series samples only changed from nothing to the characteristic absorption peaks of CH3 near the wavenumbers of 2901.4 and 2817.2.
It was found that with the increase of the initial concentration of MO solution, the HNTs series samples showed no change in CH3 characteristic absorption peak from scratch near the wave count of 2901.4 and 2817.2.
